If the opposite number of a is the largest negative integer, B is the number with the smallest absolute value, and C is the smallest three digit positive integer, then ABC =?

If the opposite number of a is the largest negative integer, B is the number with the smallest absolute value, and C is the smallest three digit positive integer, then ABC =?

The maximum negative integer is - 1, so a = 1
The minimum absolute value is 0, so B = 0
The smallest three digit positive integer is 100, so C = 100
abc=1*0*100=0
